T0 @ZZ whomv it may concern.- i

Be it known that I, J osIAH BARRETT, a resident of Bellevue, in thecounty of Allegheny and State of Pennsylvania, have `invented a new anduseful Improvementin Oil-Well Swivel-Wrenches; and I do hereby declarethe following to be a full, clear, and exact description thereof.

My invention relates to tools for handling drill-bits or other toolsused in drilling or operating Artesian Wells and for like pur poses, mytool also being applicable in general to the handling of any parts to bescrewed together when in a vertical position whether in connection withArtesian wells or any other mechanical operations. It is an improvementon Letters Patent No. 561,305, dated June 2, 1896, issued to me and isintended to meet a difficulty in the use of tools for handling heavyparts requiring to be screwed together, owing to the amount of powernecessary to unscrew or screw together such heavy parts.

My invention consists, generally stated, in providing the rotarytool-holder with a handle or handles whereby it may be turned in theswivel-ring and so arrangingthe parts that said handles will notinterfere with the proper rotation of the tool-holder even if the leveris in an inclined position.

In the accompanying drawings, Figure 1 is a side view of the tool. Fig.2 is a plan view of the same. Fig. 3 is a front view of the same, andFig. 4 is a'front view showingy a slight modification.

In the drawings the lever or frame of the wrench is indicated at 1, andthis may be supported, if desired, by any suitable crane or derrick bymeans of a chain or block, with a hook or ring passing through the eye2. This lever is forked at its forward end, being provided with the arms3, which are provided at theirouter ends with suitable bearings or eyes4. The swivelring is shown at 5, iand thisV is of the form shown in myprior patent, being open on one side, as indicated in Fig. 2. Thetool-holder or wrench portion proper, 6, is mounted to turn on this ringin the manner indicated in my former patent, being provided with aperipheral groove which engages the ring 5 and being preferably formedin two portions having one of its flanges formed as removable andinterchangeable plates in the manner described in my former patent. Thiswrench portion is openen one side, as shown, so that it can be engagedwith or disengaged from the drill-bit or other article to be handled. Inprior constructions this rotatable wrench member or tool-holder has notbeen provided with means for turning the same on the swivel-ring. Theobject of the present invention is to provide said member with a handleor handles whereby it may be turned. One of the difficulties in the wayof-applying said member with a handle or handles arises from the factthat the lever l in actual use is seldom or never in a hori` zontalposition, but, on the contrary, is generally in an inclined position,asshown in Fig. 1, and as the handle or handles in order to be edectivemust project radially beyond the periphery of the ring they will contactwith the lever 1, and thus prevent the rotation of. the tool-holder. Toovercome this difficulty, I so mount the swivel-ring 5 that it issuspended below the lever-arms 3, thus giving ample clearance for thehandles. This may be accomplished in various ways. For instance, asVshown in Figs. l to 3, rods 8, having hooked ends 9, are secured in theeyes of the arms 3, and the ring 5 is provided with perforated lugs 9a,through which the lower ends of said rods pass and wherein they aresecured bynuts 10. In Fig. 4t suspending-links 11 are shown, beingprovided with eyesat both ends and being secured to the arms 3 by meansof bolts 12 and to the ring 5 by means of bolts 13. In both cases,however, the ring 5 is mounted on the lever so as to swing withreference thereto and is suspended suciently far below the same, so thatthe radially-projecting arms will not contact with the lever in allordinary positions of the latter.

The handles are shown at 14, and preferably two such hand1es,arran geddiametrically opposite each other, are employed. Said handles may beeither formedas an integral part of the tool-holder 6 or may be separateparts suitably attached thereto. As shown in the drawings, saidtool-holder is provided with downwardly-projecting portions 15, and theIOO handles 14 are shown as integral with said portions and project outin a substantially straight line. This, however, may be varied withinwide limits without aecting the spirit of my invention.

By my improvement the toolholder or wrench proper can be turned in itsswivelring with ease, and the arrangement is such that the lever l canbe held in an inclined position without interfering with the properturning of the tool-holder.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination with a frame or lever, a ring mounted thereon but ina dierenthcrizontal plane and arranged to swing with reference theretoand having an open portion, a rotary tool-holder swiveled in said ringand having an open portion and a seat to receive the tool to be handled,and an outwardly-projecting handle or handles connected to saidtool-holder.

2. The combination with a frame or lever, of a ring suspended therefromand mounted to swing with reference thereto, a rotary toolholderswiveled in said ring and having a seat to receive the tool or otherarticle to be handled, and a handle or handles connected to saidtool-holder and projecting outwardly therefrom.

3. The combination with a forked lever or frame, of rods secured to thearms thereof and extending downwardly, a ring mounted on the lower endsof said rods and arranged to swing with reference to the lever, a rotarytool-holder swiveled in said ring and having a seat to receive the toolor other article to be handled, and a handle or handles connected tosaid tool-holder and projecting outwardly therefrom.

4. The combination with a forked lever or frame, of rods hinged to thearms thereof, a ring secured to the lower ends of said rods and havingan open portion, a rotary toolholder swiveled in said ring and having anopen portion and a seat to receive the article to be handled, and ahandle or handles connected to said tool-holder and projecting outwardlytherefrom.

In testimony whereof I, `the said JOSIAH BARRETT, have hereunto set myhand.
